One of my colleagues recently assessed the critically-ill patient.
A native english speaker was being interviewed by a random reporter. The thing is, do I have to add 'has' in this sentence?(the above sentence was the answer of the native speaker. Anyway, it would go like this:
One of my colleagues has recently assessed the critically-ill patient.
What winds me up is, there's 'recently' in the answer. Further, as for following grammar rules, mostly the 'recently' goes with 'have' coz you don't know when that had happened, right? BUT, the native speaker in this example had said that, WITH NO HAVE. Why is that? Idiomatic? Pls. Help.
(Edited my 'have' to 'has')
